Bring 1 tbsp. oil to high heat in a wok or large frying pan. Saute turkey, onions and garlic until browned. Add water chestnuts and saute over high heat for 5 to 6 minutes. Add brown sugar, soy, hoisin, and vinegar for the stir fry sauce. Saute and stir for a few more minutes until combined.

While the turkey is browning, make the special sauce by dissolving the sugar in water in a small pot over medium heat. Add hoisin, soy sauce, rice wine vinegar, ketchup, lemon juice, sesame oil, and hot chili sauce to your taste. Bring to a boil, stir in cornstarch mixture to thicken, and turn off heat.

To Serve:

- On a plate place separated lettuce leaves (cut in half if really large), ribboned carrot (use your peeler), and chopped green onion. Place warm turkey in a serving bowl, and special sauce in a separate serving bowl. Everyone makes their own. Lettuce, chicken, carrots, green onion, and then a drizzle of sauce. Wrap and then enjoy.
